As the Relativity panel finished up at Comic-Con Friday afternoon, the company released its first trailer for Haywire, the Steven Soderbergh-directed action movie starring Gina Carano.

The mixed martial arts-laden thriller features the standard revenge plot about an ass-kicking assassin who is double-crossed and comes after her betrayers. It also looks distinctly like Luc Besson's forthcoming Colombiana, which also features a female assassin in the form of Zoe Saldana.

Haywire is written by Lem Dobbs, who also scripted Soderbergh's The Limey, which itself is a twist on the one-man revenge thriller. That was very slick and tight, anchored by the performance of Terence Stamp. We'll see if Soderbergh and Carano have made this one as interesting when it comes out in January.
